An 88 should be a VRO motor...the VRO was one of the best units available...the earlier 80's oil injection was not so good. The unit does have an alarm. All you have to do to take it off is undo the alarm wire and tape it up. Then cut the oil line where it comes into the motor and plug it off. This will keep the engine from ever sucking anything else into it.
Be SURE if you take it off that you mix 50:1 before you dismantle it. Let it run on muffs for a while with the oil injection intact...once you are smoking REALLY good...you know the premix gas is in the carbs...now you can dismantle it. This keeps you from having a gas only condition for a couple minutes which could and would be bad!
There have actually been VERY few incidents of an oil pump going bad and blowing a motor...many will say different...but its true. Most blow due to another reason. Many mechs just blamed it on the oil injection. That was the easiest thing to say. A motor would drop a cylinder then they'd say oil injection..well, thats impossible...it would blow the whole engine...the oil injection injects oil into the incoming gas...not into each individual cylinder. So a cylinder does not mean oil injection. Most VRO's are very good units...ecspecially the newer ones...well late 80's early 90's. You know there is something to be said about a pump that is still going strong after 20 years of service. Think about that...where will most of the new engines be in say 20 or 30 years??
"But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
